Since the unveiling of its iPhone 4S back in October, Apple has received heaps of praise for one of its new features in particular: Siri. The digital assistant is by far the most impressive voice recognition service built into a mobile device, and it seems everyone has been blown away by it.

What many of you may not know, however, is that Siri is one of the few Apple products that wasn’t created by the team in Cupertino. Instead, Siri was created by Dag Kittlaus, a 34-year-old man from Norway, and it has made him a multimillionaire.
